Believe it or not, this intriguing little device has the amazing, chameleon-like ability to change colors according to its environment. The way it works is sort of like a one-pixel camera; turn it on and three LED lights (in red, blue and green) detect the strength of reflected light, then matches and stores the external color source. For multi-colored surfaces, the average color is reflected. Sure, it does make a perfect tool for decorators and designers… but for something as cool as this, do you really even need to find a practical use?
